A toolbox for the longitudinal assessment of healthspan in ageing mice

Abstract

The number of people aged over 65 is expected to double in the next 30 years. For many, living longer will mean spending more years with the burdens of chronic diseases such as Alzheimer’s, cardiovascular disease, and diabetes. Although researchers have made rapid progress in developing geroprotective interventions that target mechanisms of ageing and delay or prevent the onset of multiple concurrent age-related diseases, a lack of standardized techniques to assess healthspan in preclinical murine studies has resulted in reduced reproducibility and slowed progress. To overcome this, major centres in Europe and the USA skilled in healthspan analysis came together to agree upon a toolbox of techniques which can be used to consistently assess the healthspan of mice. Here, we describe the agreed toolbox which contains protocols for echocardiography, novel object recognition, grip strength, rotarod, glucose and insulin tolerance tests, body composition, and energy expenditure. They can be performed longitudinally in the same mouse over a period of 4-6 weeks to test how candidate geroprotectors affect cardiac, cognitive, neuromuscular and metabolic health.
